摘要
To assess the potential impact of oral rabies vaccination (ORV) on the occurrence of raccoon rabies in the midAtlantic region, temporal and seasonal trends of raccoon rabies cases reported in West Virginia from 1990 to 2007 were identified with both descriptive statistical analysis and exploratory time series analysis. Raccoon rabies cases in the non-ORV region maintain an enzootic pattern and increase over time; a bimodal seasonal pattern is observed with a large peak in April and a smaller peak in August. The results of the model indicate that the effect of the ORV intervention to control raccoon rabies was statistically significant. ORV should be attempted in other enzootic raccoon rabies areas.
